Hi all,

After merging the block tree, today's linux-next build (powerpc
ppc64_defconfig) produced this warning:

fs/io_uring.c: In function 'io_close':
fs/io_uring.c:3415:3: warning: ignoring return value of 'refcount_inc_not_zero', declared with attribute warn_unused_result [-Wunused-result]
 3415 |   refcount_inc_not_zero(&req->refs);
      |   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Introduced by commit

  62e0c6b73a2c ("io_uring: make submission ref putting consistent")
